Bug ID: 1203811
           Summary: update to go1.4 :: for etcd requirement
           Product: Fedora
           Version: 20
         Component: golang

Since golang is forward compatible, all applications that build with go1.3.3
will stay compatible. But allow upstream requirements of go1.4 to be satisfied.
